Improvement in apparatus for exhausting and purifying gases



UNITED STATES PATENT FFICE.

PETER MUNZlNGER, OF PHILADELPHIA, PENNSYLVANIA.

4 g Specification forming part of Letters Patent No. 118,472, dated August 29, 1871.

To all whom it may concern:

Be it known that I, PETER MUNZINGER, of the city and county of Philadelphia and State of Pennsylvania, have invented anew and useful Apparatus for Exhausting and Washing Gas.

The invention consists of the mechanism hereinafter shown and described of exhausting and washing gas by water, steam, or other gaseous iiuid or liquid.

Figure l is a vertical section. Fig. 2 is a plan vlew.

A is a vessel7 supplied with water or other iiuid to a suitable depth; it connects, in this instance, with the condenser of the gas-works by means of the nozzle B. C is a bent or other pipe, called the induction-pipe,Y its lower end b communicates with the vessel A beneath the water level; its upper' end o terminates in a tapering contracted outlet inthe pipe D of the vessel A. E is a short cylindrical annular distributing, chamber, which embraces the upper end of the pipe D 5 it has a nozzle, F, whereby communication is had with hydraulic main of the works. The chamber E communicates with the pipe D by means of the openings d arranged around the said pipe; they have sufficient capacity to pass all the gas generated by the retorts without causing any resistance or back pressure. A rotary pump, G, is placed in the pipe C for drawing and forcing the i'luid from and to the chamber or vessel A through the pipes C and D. The end c of the pipe C should be contracted, as shown at Fig. l, to increase the Velocity of the discharge into the pipe D, and thereby more readily overcome all the resistances. y

On the pump G being set rapidly in motion by belting, gearing, or other suitable means, the liuid is drawn from the vessel A, forced through the pipe C, and discharged from the contracted outlet c at a high velocity, in a continuous stream into the pipe D, thence back into the vessel A. The gas from the retorts enters the chamber E through the nozzle F, thence is sucked or drawn into the pipe D through the openings d; the force or impetus of the iiuid issuing from the outlet c is imparted to it, whereby it is forced down the pipe D into the chamber or vessel A and out at the nozzle B with a propulsive flow sufficient to overcome the accumulated resistance of the water joints and other resistance.

Besides serving as an eXhauster, the above-described mechanism serves to scrub and wash the gas and take from it all tar and ammoniacal liquor, which is removed from it during its frictional contact with the water in its passage down the pipe D into the vessel A, and is deposited in the water of the same. The water in the cistern must be renewed when too thoroughly impregnated with tar, Svc.

I am aware that other mechanical devices can be employed for drawing and forcing the water from and to the vessel A other than the rotary pump Gr; therefore I do not confine myself to its use. I also do not coniine myself to the propulsive force of water for exhausting and washin g the gas. The pipe G can be converted into a steam-pipe, and a jet of steam issuing from the contracted nozzle o can be used for exhausting' and washing, in which case the vessel A must contain enough water to condense the steam as it enters it, and the connection of the pipe C at Z with the vessel A must be discontinued and an attachment made with some steam-generating device, by which the pump G is entirely dispensed with.

I claim- The tank or vessel A, the induction-pipe C, with or without the pump Gr, and the annular or other distributing-chamber E, for the purpose shown and described.

In testimony whereof I hereunto sign my name in presence of two subscribing witnesses.
